pulseaudio and alsa on ubuntu 12.04 server
- by Dan
I am running ubuntu 12.04server, and trying to get pulseaudio working. I followed the instructions at How do I run PulseAudio in a headless server installation?
At the moment, pacmd list-cards is reporting 0 cards, aplay will only playing sound when I run it as sudo, and running alsamixer as sudo also works, but running it as my user produces "cannot open mixer: No such file or directory"
As far as I can tell, this means the the kernel module for my sound card is in fact loaded. I have already tried adding my user to the "audio" group, but this does not help. The permissions on the devices in /dev/snd are all
crw-rw---T 1 root audio 116
I noticed on an ubuntu 12.04 desktop, that the file permissions are slightly different. On the desktop, they are
crw-rw---T+ 1 root audio 116
My questions are
1) How do I get aplay to work without running it as sudo on the server
2) Is there anything special I need to do to make pulseaudio work at this point.
